Description

Left and Right Switching Assembly for Cassette Handle}

The present invention relates to a left and right hand switching assembly, and more particularly, to a left and right hand switching assembly for a cassette handle.

In general, a door lock includes a handle, a mortise and accessories, and refers to a part in charge of opening and closing and security of a door. Here, the mortise is installed inside the door and connected to the handle so that the door can be opened or closed by locking or unlocking the latch bolt by moving the latch bolt from side to side according to the rotation of the handle.

These door locks are classified into left-handed type and superior type. When the door lock and mortis are installed on the right side, the door lock is called the left hand type. On the contrary, the hinge of the door is on the right side, and it The door lock when the mortis is installed on the left is called excellent type.

That is, the left-hand type makes it easier for the user to open and close the door with the left hand, and the superior type allows the user to open and close the door with the right hand conveniently.

However, in the conventional door lock handle, the installer determines the insertion direction of the inner handle and the outer handle according to the opening direction of the door in the process of installing the door lock on the door in the left-hand or right-hand type, and then works.

Therefore, there is a disadvantage that not only takes a lot of work time, but also the durability of the device is deteriorated due to loose screws due to the negligence in combining the inner handle and the shaft while the installer pays attention only to the direction of insertion of the handle.

In addition, since the conventional door lock handle needs to be disassembled and reinstalled in order to change the left and right after installation, a problem of poor workability has been raised.
